ARCH BRICK.

original application filed May 23, 1922,

This invention relates to the arch brick such as commonly used in locomotives and is a division ofiny application Serial No.

I 563,043, filed May 23, 1922, which illustrates the method of manufacturing the arch bricks shown herein. j

The common forniof arch brick is made in one piece and owing to the large sizes of some of the bricks there are difliculties in the man-' ufacture owing to liability of the bricks, While ,still plastic, tolose. their shape in handling. 'Heretofore, it'has been practically impossible to manufacture these size bricks chines, owing to this difticulty. Another disadvantage incident to the pi'es ent form of brick is that in service these bricks 011 mil-- are subject to the veryliigh temperature a locomotive fire box and consequently are con .stantly expanding and contracting With the variations ofthetemperature. The cumulative effect of the strains caused by this expa nsioii andcontraction "results in spalling or chippingordinarily, andin some cases, breakage of the brick.

It'ist-he primary object my invention to manufactured by machine and in Which the strains encountered in serviceare, to a cer- I tain extent, reduced and the cumulative effect over the whole brick is'eliminated. In other Words, by building the brick in sections the strain is localized in each section and prevented from spreading over the entire brick;

Another object of my invention is the provision of a laminated brick in which the units are provided on contacting surfaces with cooperating pro ections and recesses by means.

of which the bricks are held imposition prior to bonding; V i V v v A further object is the provision of a laini nated brick Which can be made in different I shapes and sizes, adapted for use in different places in the fire box and for different tube hereinafter appear, or. are incident to my inventio-n, I attain by meansof a. construction,

the preferred embodiments of Which areillustrated in the accompanying drawings,

trates What is known as a curved middle v In Fig. 1 I have illustrated the usual type of locomotive fire boxiA with the arch supporting tubes 1' upon which is supported the arch B composed of my improved bricks. These bricks are made jof la'minae or units 2 (see Figs- 2, Sand 4L) by applying-a suitable bonding material such as high temperature furnace cement commonly used in the 7 ,art to the surfaces of the individual units 2' overcome these difficulties by the provision of a sectional or laminated brick vvhiclrcan be,

and then stacking these units to form I the brick, abrick composed, of four unitsbeing la conii'non size. provided With one or more pro ections 3 and the opposite side is provided With corresponding recesses l, the projections on one unit fit ting into the recesses on the adjacent unit to hold the-m in place during handling prior to sembled'the complete brick Will present a tube engaging surface along the entireenrhas illustrated in Figure l.

desired the brick is burned and the bonding material s'et in a manner Well known in the art; If de shed the individual sections may be burned before they are stacked and terial then applied and fixed.

Thebrick so far considered, shown in Fig- I ure 4, is only one of the manyforms required for locomotive arches. Anotherv form is illusthebonding ma-'.

One side of each unit 2 is i.

. I o 'After the individual sections have been formed and stacked in: proper relation to make the particular form of brick supporting surrface.

, shorter at both ends of trated in Figs. 7, 8 and 9 which is composed of alternate glong andishont units 6 and 7. At one end these units are all placed flush so that the brick at this end presents a continuous All :the other end the units project alternatelynthe supporting surface of one unit extending beyond that of the adjacent units. A brick of the character illustrated in Fig. 8 can be used in combination with similar bricks in the maner illustrated in Figure 9. Here the continuous supporting surface ;of the brick rests on the tube and with thebricks in leaning position the al- ,te'mate projecting portions of one brick will .lit into and engage the recessed portions of the cooperatingbrickandthe bricks thus held HLP'OSLUOIL This type ofbrick may also be used as illustratcd in Fig. 10 where one brick spans .the distance between two tubes, the projecting unitssup porting the 'biiickat one end. 1f desired the projecting portionsof the brick may be chipped or lcnocked off and thehriok used to take care of ashonter span, as illustrated in Fig. 11. In this case the 'tube engaging surfaces of the shorter units support one end of the brick.

In Fig. 12 is illustrated a brick composed of alternate long and short units but in this case the longer units roject beyond .the

the brick.

InFigs. l3 to'16 a half tongue, half groove form isillustrated. Tavo units are made with a projectingtongue '8 and two units with a groove 9 and these fourunits are arranged as shown in F 13 to form a complete brick which hasat' one end a tongue eXtendi-nghalf way across the width of thebrick and a groove extending across the other half of the width of the brick. The brick maybe assembled in pairs in reversed relation with their inner ends leaning against each other, the tongue in one brick fitting into the groove in the other.

The side brick 10, rllustrated'in Fig. 17 is made up of units illustrated in Fig. 18. This brick is used between :the outside tube and the side sheet, thesurfface 5 resting on the tube and the surface 11 resting against the side sheet, the brick being in leaning position.

Fig. 19 illustrates a unit used to make a brick similar to that shown in Fig. 4 butin this case the brick is curved intsead of being flat. i

I claim 1. A refractory member composed of laminzn of different lengths.

2. Au arch brick co osed of a plurality of long units and a pluliiility of short units alternated. .3. A laminated arch brick composed Of units having a tongue and other unitshaving a groove and all arranged to form a half tongue and groove brick for use in spans w hcretwo bricks are asesnibled in traversed relationt-o lean against each other. 7

4. An arch brick constructed of laminae 0f (liti'ferent lengths which are arranged to ,provide a support engaging surface at one end and projecting and receding support engaging surfaces at the other end.

5. An arch brick constructed of laminae uof different lengths which are arranged to-provide a support engaging surface at one end and projecting and receding support e taging surfaces at the other end,"the receing surfaces making the 'brick ac-eonimodable to a span of less clime nsionwhen the proiecting surface is broken away.

In testimony whereof, I have hereunto signed my name.
